A ITORNEY UNITED STATES WILLIAM BOBEK, 0F ASTORIA, NEW YORK.

INVISIBLE HINGE.

Application filed January 6, 1921.

T 0 all 10 720m it may concern Be it known that I, WVILLIAM BOBEK, a citizen of the United States, residing at Astoria, in the county of Queens and State of New York, have invented certain new and useful Improvements in Invisible Hinges, of which the followingis a specification.

The main object of this invention is the provision of an invisible hinge for automobile doors, so designed as to be entirely concealed when the door is closed, and presenting a neat, compact appearance when the door is open. v

The above and other objects will become apparent in the description below, in which like-named characters of reference refer to like-named parts in the drawings.

Referring briefly to the drawings. Fig. 1 is a fragmentary perspective view of an automobile body equipped with my hinge,

illustrating the principle thereof.

Fig. 2 is an enlarged perspective view of the hinge in extended position.

Fig. 3 is a substantially central cross-sectional view of my hinge, taken on a horizontal plane, the hinge being collapsed.

Referring now in detail to the drawings, the numeral 1 represents one of the members of my hinge and 2 the other, the same being provided with recesses or pockets 3 and 1, respectively, into which the links of the hinge are adapted to be folded and concealed when the same is collapsed, as will become apparent.

Against the inner wall of the pocket 3 are rigidly attached a plurality of spaced apart, like lugs 5 which may be made integral with the wall, and rotatably attached to these lugs are a plurality of similar cars 10 integral with a member 9. These ears, as well as those to be described, mesh with each other interengagingly. Similarly, ears 6 integral with the inner wall of the pocket 4 mesh with ears 8 of a member 7. Relatively Specification of Letters Patent.

Patented Mar. 21 1922.

Serial No. 435,364.

longer links 13 and 1 1' are rotatably secured to the rear portions of the inner walls of the pockets at 16 and 15, respectively, and the links 13 alternately cross the links 1-1, as apparent in Fig. 3.

Ears 11 extend from the opposite end of the member 7, and are rotatably secured to the free ends of the links 13. Similarly cars 12 extend from the opposite end of the member 9 and are rotatably attached to the free ends of the links 14. The links 13 and 14 are pivotally secured to each other in alternate relation at 19.

As is readily apparent in Fig. 2, when the members 1 and 2 are rotated toward each other in closing or collapsing the hinge, the members 7 and 9 will fold over into their respective pockets, and will carry with them the afore-mentioned free ends of the links 13 and 14. The final position of the various members and links is apparent in Fig. 3, the entire mechanism of the hinge being con-, cealed when the hinge is collapsed.

As shown in Fig. 1, the members 1 and 2 are secured by screws 18 to the wall and door of the automobile, respectively. This figure readily illustrates the concealed char acter of the hinge without further explanation.

I claim:

A concealed hinge comprising an opposed pair of casing plates having chambers in their adjacent sides, lugs extending from the bottom walls of the chambers, the lugs on one plate being offset to those on the other, plurally forked links hingedly engaging said lugs, other plurally forked links hingedly engaging between the first named lniks, and a single pivot pin connecting all of said hingedly engaged links whereby all of said links may be concealed within the chambers of said plates when closed.

In witness whereof I afiix my signature.

WILLIAM BOBEK.
